Abstract (en)
In the present invention, a communication hole disposed in a rotor 60 on the center side of a lower holder 72 is eliminated, and accordingly even if lampblack produced at high temperatures is sucked, it is possible to prevent large drops of mist which do not exist at low temperatures from being sucked, making it possible to avoid the decrease of the separation efficiency. Further, concerning oil which is to move downward in and be discharged from the inner peripheral surface 22f of the middle case 22, and concerning a swirl flow (wind) which is caused by rotation of the rotor 60, a first partition wall 31b provided on the upper surface side of the lower partition wall member 31 prevents that oil from being carried by that swirl flow in a clearance 43a. Here, the clearance 43a is located radially outside in the lower portion of the rotor 60 and serves as an escape path of blow-by gas flowing at an ultra high flow rate. Further, the first partition wall 31b prevents that oil from staying on the inner peripheral surface 22f of the case 22. This enables oil which moves downward and gas which moves in the opposite direction to pass each other without interference. Consequently, the oil can be continuously discharged to the lower case 21 from the separation chamber 43 having the rotor 60 to avoid accumulation of oil in the separation chamber 43. Accordingly, the rotor 60 can be prevented from submerged in the oil.
